Facial identification techniques

ABSTRACT

As the use of facial biometrics expands in the commercial and government sectors, the need to ensure that human facial examiners use proper procedures to compare facial imagery will grow. Human examiners have examined fingerprint images for many years such that fingerprint examination processes and techniques have reached a point of general acceptance for both commercial and governmental use. The growing deployment and acceptance of facial recognition can be enhanced and solidified if new methods can be used to assist in ensuring and recording that proper examination processes were performed during the human examination of facial imagery.

RELATED APPLICATION DATA

This application claims the benefit of and priority under 35 U.S.C.§119(e) to U.S. Patent Application No. 62/168,351, filed May 29, 2015,entitled “Facial Identification Techniques,” which is incorporatedherein by reference in its entirety.

BACKGROUND

While both finger and facial images exist as images for processing andcomparison, there are key differences between the two:

-   -   Fingerprint images are black and white while facial imagery can        be color or black and white.    -   Fingerprints are caused by touching a surface (which stabilizes        the capture) while facial images are captured with little or no        control over the subject.    -   Finger details (ridge flows and minutia patterns) are a discrete        type of image pattern whereas facial features vary widely across        gender, race, age, hair, pose, lighting, facial obstructions,        etc.    -   There are many accepted courses and career tracks for the        training of fingerprint examiners, whereas there are no current        public courses for the training of facial examiners.

Human examiners can be presented with facial images for comparisons intwo distinct ways:

-   -   Computer based algorithms can be used to produce a list of        candidates for review after searching a probe image. This is        referred to as “Facial Recognition” or FR.    -   Two images can be manually selected for review.

In both cases, it is up to the human facial examiner to analyze the twoimages and produce a final decision whether the person in both images isof the same person. This process has several commonly used definitions:

-   -   Facial Examination (FE): A formal systematic examination of two        facial images to determine if the same person is shown in both        images. An example of this systematic examination technique,        broadly accepted for use in fingerprint examinations, is called        ACE-V (Analysis, Comparison, Evaluation, and Verification).    -   Facial Identification (FI): The human-based examination of the        similarities and differences between two facial images with the        goal of determining if the same person is shown in both.

In any current operational environment using facial biometrics, the actof the FI is where a human facial examiner (or a group of examinersworking together) is responsible for making a decision as to whether thesame person is shown in two distinct images being compared.

DETAILED DESCRIPTION

Embodiments of systems and methods described herein can operationallyensure that a facial examiner follows specific predefined guidelines orbest practices during a facial identification process. While accreditedand accepted training for facial examiners evolve, an operational ownercan integrate the appropriate guidelines or best practices directly intothe actual facial identification processes used in real operationalenvironments or training courses. Such guidelines or best practices caninclude a list of specific facial components that should be reviewed forevery instance of a human facial examiner performing FI.

In one exemplary embodiment, the list of facial components includes, butis not limited to, one or more of skin, face/head outline, face/headcomposition, hairline or baldness pattern, forehead, eyebrows, eyes,cheeks, nose, ears, mouth, chin or jaw line, neck, facial hair, faciallines, scars, facial marks, and alterations. Other embodiments of thelist can include a different set of fewer (or more) facial components.Such guidelines or best practices can also include instructions for eachof these facial components to train, assist, or guide the facialexaminer when performing the FI for that facial component.

Embodiments of systems and methods described herein directly integratethe list of predefined facial components into the FI process:

-   -   1. Providing a direct on-screen reference to the list of facial        components and their associated anatomical terminology during        the facial review.    -   2. Displaying the areas on the facial components on the face as        defined by the guidelines or best practices.    -   3. Optionally ensuring the facial examiner looks at every facial        component in the list.    -   4. Audit that every facial component in the list is reviewed by        the facial examiner.

Exemplary Steps:

Step 1:

The human facial examiner at a workstation sets the eye locations forboth facial images (i.e., probe and candidate images). This operationcan be done by manually reviewing and possibly (re)centering the eyelocations over the left and right eye locations, as shown in FIG. 1 andFIG. 2 (Image 1 104 and Image 2 204). For example, one or more of theeye locations can be dragged-and-dropped to an updated center locationusing an input device such as a mouse. This setting of the eye locationsis done to create landmarks so that all the facial components to bereviewed can be correlated to the eyes.

Step 2:

After the eye locations for both facial images are reviewed and acceptedby the user at the workstation, both images 104 and 204 can be displayedside-by-side, as shown in the exemplary display in FIG. 3.

At this point, two windows 404 and 408 can appear as shown in FIG. 4that are used during the enforced facial identification process.

-   -   1. In a first window 404 (which can optionally be a standalone        window), any referenced document that the operational owner has        decided to utilize in this facial identification process can be        displayed to the user (i.e., facial examiner). The document can        be placed in at any optimum location within the user's computer        desktop environment.    -   2. The predefined list of the facial components mandated by the        guidelines or best practice is displayed to the user in this        window 404, which can also be placed in an optimum location        within the user's computer desktop environment. In addition to        displaying the list of facial components to be examined, other        information, such as an identification information (ID), viewed        status, and the results of the review can be associated with        each facial component and optionally shown in one or more        windows that can optionally be updated as the steps taken by the        examiner are completed. Table 1 below provides an example of        what may be presented to the user in this second standalone        window.        -   IDs may be associated with the facial components that must            be reviewed; the IDs can enumerate and prioritize the facial            components.        -   The default state of Viewed Status can be NO.        -   The default state of the Results (Similarity/Difference) can            be NULL or empty.

Step 3:

At this point the user can sequence from facial component A through thelast facial component to be examined during the FI process as shown inFIGS. 5-21. In one embodiment, the list of facial components identifiesevery facial component that must be examined for the FI process to beconsidered properly performed and in conformance with a particularstandard, regulation and/or guideline. As the facial components aresequenced:

-   -   Visual boxes (or other highlighting technique(s)) can be shown        to the user overlaid onto the facial images, which represent the        specific facial component to be reviewed (See FIGS. 5-21);    -   The Viewed column is set from “No” to “Yes”, as the user        examines the facial component—this can optionally be        automatically performed as the user/examiner views each specific        facial component and steps to review the next; and    -   The Similarity/Difference column can be set by the user        indicating whether the specific facial component:        -   shows similarity (S),        -   does not show a similarity (D), or        -   cannot be evaluated (N/A).    -   The referenced guideline or best practice document can        optionally be automatically repositioned to show each specific        facial component within the context of the document.

It is to be understood that the order in which the facial components areexamined may differ from that described below. As discussed, FIGS. 5-22shown exemplary comparisons for various facial features. As illustratedin these exemplary Figures, a visual box(s) and/or highlight is placedaround the feature(s) to be compared. Specifically, FIG. 5 shows anexemplary comparison of face/head outlines, with guidelines for thecomparison shown in window 404. FIG. 6 shows an exemplary comparison offace/head composition, with guidelines for the comparison shown inwindow 404. FIG. 7 shows an exemplary comparison of hair/baldnesspatterns, with guidelines for the comparison shown in window 404. FIG. 8shows an exemplary comparison of a forehead region, with guidelines forthe comparison shown in window 404. FIG. 9 shows an exemplary comparisonof eyebrows, with guidelines for the comparison shown in window 404.FIG. 10 shows an exemplary comparison of eyes, with guidelines for thecomparison shown in window 404. FIG. 11 shows an exemplary comparison ofcheeks, with guidelines for the comparison shown in window 404. FIG. 12shows an exemplary comparison of noses, with guidelines for thecomparison shown in window 404. FIG. 13 shows an exemplary comparison ofears, with guidelines for the comparison shown in window 404. FIG. 14shows an exemplary comparison of mouths, with guidelines for thecomparison shown in window 404. FIG. 15 shows an exemplary comparison ofchin/jaw lines, with guidelines for the comparison shown in window 404.FIG. 16 shows an exemplary comparison of neck, with guidelines for thecomparison shown in window 404. FIG. 17 shows an exemplary comparison offacial hair, with guidelines for the comparison shown in window 404.FIG. 18 shows an exemplary comparison of facial lines, with guidelinesfor the comparison shown in window 404. FIG. 19 shows an exemplarycomparison of scars, with guidelines for the comparison shown in window404. FIG. 20 shows an exemplary comparison of facial marks, withguidelines for the comparison shown in window 404. FIG. 21 shows anexemplary comparison of alterations, with guidelines for the comparisonshown in window 404.

Step 4:

FIG. 22 shows an exemplary embodiment of embedded synchronizedmagnifiers 2204 where the eyes can be magnified to assist theuser/examiner. These synchronized magnifiers can be moved to any part ofthe faces and are correlated to show the same portions of the faces 104and 204 at the same time. FIG. 23 shows an exemplary embodiment of afirst increased zoom feature 2304 of the embedded synchronizedmagnifiers and FIG. 24 shows a second exemplary embodiment of anincreased zoom 2404 of embedded synchronized magnifiers. Here, theexaminer has zoomed in significantly on one each in each of the probeand candidate images.

As each facial component is displayed to the user, a pair ofsynchronized magnification areas can optionally be displayed over theimages allowing the user to zoom in on any discrete area, as shown, forexample, in the above figures. At any time the size and zoom of themagnifiers can be controlled, updated or modified by the user.

Step 5:

In one embodiment, the user cannot complete the facial identificationprocess unless:

-   -   All facial components in the list have been reviewed by the        user; and    -   The user has specified whether for each facial component there        is a similarity, a difference, or it cannot be evaluated.

The user can Exit the facial identification process at any stage in theprocess, but a decision as to whether the same person is in both imagescannot be evaluated in such an event.

At the end of the entire facial identification process, a permanentauditing record may optionally be saved which confirms:

-   -   Two images were reviewed in accordance with a predefined process        (e.g., guidelines or best practices);    -   On a specific date, a user on an operational workstation        performed the facial identification controlled by the predefined        process; and    -   A final decision by the human examiner was arrived at.

FIG. 25 illustrates an exemplary system that can be used in conjunctionwith the above steps. The exemplary system includes aprocessor/controller 2504, memory 2508, I/O interface 2512, GPU 2516,facial components database 2520, facial component manager 2524, facialcomponent list manager, verifier and auditor 2528, magnifier module2532, folder manager 2536, dynamic report generator 2540, audit reportmodule 2544, guidelines 2548, one or more displays 2552, one or more I/Odevices 2556, and one or more remote biometricsystem(s)/databases/back-end systems 2560 (connected via thenetwork(s)).

In operation, and in accordance with one exemplary embodiment, thesystem can be configured to resemble an email system. While otherconfigurations are certainly possible, the emulation of an email systemin terms of workflow at least assists with management and organizationof the various images.

In accordance with one exemplary embodiment, the facial componentmanager 2524, in conjunction with the processor 2504, memory 2508, GPU2516 and facial components database 2520 present a probe sample to theuser at display 2552. This probe sample can be forwarded to a back-endsystem, such as remote biometric system 2560 to perform initialmatching. Once sent, the folder manager 2536 can place the sent probesample in a “sent folder”— the “sent folder” representing that the probesample has been sent away for a search to be done by the back-end system2560. In conjunction with the search being sent out, a demographicfilter and/or other filtering criteria can be sent with the image tohelp reduce the number of false positives received back from theback-end system.

On receipt of the results from the back-end system 2560, an indicationcan be placed in an “Inbox” by the folder manager 2536 alerting theuser/examiner that there are probe and candidate samples ready to review(these results can be stored in the facial components database 2520).The GPU 2516 can provide to the user/examiner, on displays 2552, acandidate screen that shows all candidates returned by the back-endsystem 2560. This candidate screen, in conjunction with the facialcomponents database 2520 and facial component manager 2524, can befiltered to reduce the number of candidates. For example, auser/examiner can select Yes, No or Maybe, to reduce the number ofcandidates to a more manageable number with the No candidates optionallybeing removed from the display.

Next, the user/examiner can perform a detailed review of the probesample to one or more of the candidates as shown in FIGS. 3-25. Duringthe comparison, the user/examiner can one or more of calibrate thefaces, perform a visual alignment of the faces, adjust scaling, adjustcolors, and in general adjust any one or more of the characteristics ofthe probe and candidate sample either in unison or separately. Ingeneral any type of image adjustment can be performed including one ormore of invert, color channel adjustment, greyscale adjustment, CYMKadjustment, or the like.

As the user/examiner reviews each of the facial characteristics, thefacial component list manager, verifier and auditor 2528, in conjunctionwith the processor 2504, facial component manager 2524 and facialcomponent database 2520, tracks the actions and records the results ofthe comparisons. The user/examiner during this process can takesnapshots of particular features of interest with these snapshots beingcaptured and added into a report which is being dynamically generated bythe dynamic report generator 2540. These snapshots can then optionallybe supplemented with one or more comments from the user/examiner.

Also, at any time, the guidelines 2548 can be retrieved and displayed tothe user/examiner. These guidelines can be dynamically liked to facialfeatures such that if the user/examiner clicks on a particular feature(such as the eyes) the corresponding guidelines (such as in a PDF, textor other document format) for eye comparison can be displayed—such asthe guideline shown in FIGS. 10-21 in windows 404.

Optionally, the audit report module 2544 can keep track and store one ormore actions taken by the user/examiner, with the stored informationusable for one or more of training, to confirm lack of biases, toidentify errors and/or to ensure any applicable guidelines have beencomplied with. This audit trail can then be stored in the facialcomponents database 2520 (or in general at any location and/or printedor sent to a destination such as via email) along with any informationabout the probe and/or candidate.

Optionally, the dynamic report generator 2540 can generate one or morereports. These reports can be compiled at the end of the review process(e.g., a finalization report) and/or dynamically created as thecomparisons are made. As one example shows in FIG. 26, the report 2604includes one or more sections populated with information regardingcomparison decisions that were made. The exemplary sections include:“Snapshot”, “Feature”, “Same/Different”, “Snapshot Images”, “Comments”,and “Data Path.”. Snapshot can indicate a sequence number for thesnapshot. Feature can indicate which feature the snapshot is for.Same/Different can represent whether the examiner believes the featureis the same or different. Snapshot images can include images of thecomparison. Comments can include any examiner comments and data path caninclude information regarding the source file for the captured images.

As discussed above, the system can optionally be configured in anemail-like manner. Thus, the system can have, for example, a reviewedfolder, indicating that the examiner has reviewed and/or completed thecomparison. The system can also optionally include a “needs attention”folder for situations where there has been an anomalous error.

For all of the various information, captures, reports etc. describedherein, metadata can be associated with that information and canoptionally be used for sorting (name, date, ID, etc.) or the like.

FIG. 27 outlines an exemplary method for performing facial recognition.In particular, control begins in step S2704 and continues to step S2708.In step S2708 a probe sample is loaded for display. Next, in step S2712,one or more candidate samples are loaded for display. Then, in StepS2716, the samples can be displayed in a side-by-side or other manner.Control then continues to step S2720.

In step S2720, a predefined list of facial components to be compared ismaintained and managed. As discussed, an exemplary embodiment caninclude one or more of the following facial components that requirecomparisons: skin, face/head outline, face/head composition, hairline orbaldness pattern, forehead, eyebrows, eyes, cheeks, nose, ears, mouth,chin or jaw line, neck, facial hair, facial lines, scars, facial marks,and alterations. Next, in step S2724, the user is guided through theexamination process with reference to the predefined list. Then, in stepS2728, the user is optionally provided one or more ofguidelines/reference material/instructions/examples for the specificcomparison being made. Optionally further, the user can have theirattention drawn to a specific facial feature being compared. Optionallystill, the system can automatically update the display with one or moreof the guidelines/reference material/instructions/examples/drawings tocorrespond to the facial component currently being examined. Controlthen continues to step S2732.

In step S2732, the predefined list can be updated as each facialcomponent comparison is completed. Next, in step S2736, the user canoptionally be required to complete a current comparison before beingallowed to proceed to a next comparison. Then, in step S 2740, useractions can optionally be logged as discussed. Control then continues tostep S2744.

In step S2744, the user can optionally record one or more ofnotes/comments/images/comparison results associated with one or more ofthe comparisons—with one or more of these items optionally being addedto a report. Next, in step S2748, the user can optionally be required toperform all comparisons for completion of the facial identificationprocess—with the user optionally being returned to complete anyincomplete comparisons. Then, in step S2752 an audit report canoptionally be generated. Control then continues to step S2756. In stepS2756, a finalization report can be generated with control continuing tostep S2760 where the control sequence ends.

In accordance with yet another optional embodiment, the system caninclude an application that can run on a desktop (e.g., ForensicSpectacles) which allows a user to control and directly push any twoimages currently displayed anywhere on the desktop directly into a 1:1examination screen. This allows a user to, for example, see facialexpressions—this allows “one click facial review.” In another exemplaryembodiment, the linked magnifiers can “snap” examination areas ofinterest into an off screen repository where they can then be directlypublished into a finalization document. This allows users to create thefinal examination report as part of their workflow which can, forexample, dramatically shorten the time to create the final report.

In accordance with another exemplary embodiment, the checklist(predefined list) can also lay out the facial components. Another windowcan optionally be shown that references the correct and acceptedanatomical definitions of the facial components. Both the checklist andthe definitions can be synced to the facial component the examiner iscurrently reviewing. This can provide for each facial component 1) achecklist of what to look for, and 2) the proper anatomical terms forthe specific component. Therefore, the examiner can be given a fullsuite of items and proper anatomical definitions for managing the facialidentification. FIGS. 28-37 show examples of accepted anatomicaldefinitions of the facial components which are available fromfiswg.org—Facial Image Comparison Feature List for MorphologicalAnalysis, which is incorporated herein by reference in its entirety.

Additionally, the following two documents, which are also incorporatedherein by reference in their entirety, provide information andbackground: SWGFAST, Document #10, Standards for Examining FrictionRidge, Impressions and Resulting Conclusions (Latent/Tenprint) atwww.swgfast.org/documents/examinations-conclusions/121124_Examinations-Conclusions_2.0.pdfand SWGFAST, Document #8, Standard for the Documentation of Analysis,Comparison, Evaluation, and Verification (ACE-V) atwww.swgfast.org/documents/documentation/121124_Standard-Documentation-ACE-V_2.0.pdf.
